Mean

Compute the arithmetic mean of element values.

double vector::Mean();

double matrix::Mean();

vector matrix::Mean(
ENUM_MATRIX_AXIS axis // axis
);

Parameters

axis

[in] Axis. ENUM_MATRIX_AXIS enumeration value (AXIS_HORZ — horizontal axis, AXIS_VERT — vertical axis, AXIS_NONE — no axis, calculation along whole matrix).

Return Value

Arithmetic mean of element values.

Example

   matrixf matrix_a={{10,3,2},{1,8,12},{6,5,4},{7,11,9}};
   Print("matrix_a\n",matrix_a);

   vectorf cols_mean=matrix_a.Mean(AXIS_HORZ);
   vectorf rows_mean=matrix_a.Mean(AXIS_VERT);
   float matrix_mean=matrix_a.Mean();

   Print("cols_mean ",cols_mean);
   Print("rows_mean ",rows_mean);
   Print("mean value  ",matrix_mean);

   /*
   matrix_a
   [[10,3,2]
    [1,8,12]
    [6,5,4]
    [7,11,9]]
   cols_mean [6,6.75,6.75]
   rows_mean [5,7,5,9]
   mean value  6.5
